Here is a problem I was working on but I do not have a solutions manual because Its an old text book. I would just like someone to look over my work. 1. The problem statement, all variables and given/known data Calculate the pH of a 0.67 M NaClO solution. NaClO -> Na+ + ClO- ClO- + H2O -> HCLO + OH- Kw = 1.0*10^-14 Ka HCLO = 3.5*10^-8 Could you please check if these constants are correct. 2. Relevant equations Kb = Kw/Ka HCLO pH = -log [H+] 3. The attempt at a solution Kb = Kw/Ka HCLO = 1.0*10^-14/3.5*10^-8 = 2.86 * 10^-7 With Kb we can solve concentrations for OH- Kb = [HClO] [OH-] / [ ClO-] 2.86 *10^-7 = (x)(x) / (0.67-x) Quadratic Formula x = 4.38 * 10 -4 M [OH-] = 4.38 * 10^-4 M [H+] [ OH-] = 1.0 *10^-14 [H+] = 1.0 *10^-14 / 4.38 * 10^-4 M = 2.28 * 10^-11 M pH = - log[H+] = - log( 2.28 * 10^-11) = 10.64 This is a reasonalbe result. My last question is how do I turn off overtype when I am preparing a new thread? Thank you for your time.
